Description
Summary:Fiber optics can serve as optical sensors to determine efficient optical system in a variety of criteria such as reach, functional, the sensitivity and accuracy of the optical system [1-4]. The FRA circuit is used in the form of a pre amplifier that can amplify light signals sent via optical fiber before the light signal is received by the photo detector so that the weakening of the signal to noise ratio caused by thermal noise in the photo detector can be suppressed [13, 14]. The optical fiber communication system consists of a block of transmitters that function to convert electrical signals into light signals, optical fiber transmission medium and detectors as sensors of visible or invisible light signals and convert them into electrical signals [21]. Figure 5 shows the relationship between the distance of optical fiber transmission and Q factor, which is the further the transmission distance, the smaller the Q factor value is obtained. 4.Conclusion Raman amplifier circuit system has been successfully simulated from 10-50 km with 1350 nm wavelength source, where 0.1 W pump power is run with several iterations corresponding to various distances.
